Abstract

Предлагаются композиции и способы для сконструированных клеточных линий и экспрессионных систем, которые позволяют экспрессировать рекомбинантные белки в эукариотических клетках и облегчают их выделение. Также предлагаются клеточные экспрессирующие системы, способные экспрессировать белок, представляющий интерес, по существу, свободный от связанного белка клетки-хозяина.Compositions and methods for engineered cell lines and expression systems are proposed that allow the expression of recombinant proteins in eukaryotic cells and facilitate their isolation. Cellular expression systems are also proposed that are capable of expressing a protein of interest substantially free of the associated host cell protein.
